摘要
以戊糖收率为评价指标,对竹黄半纤维素水解条件进行了优化试验。结果表明:竹黄水解的最优条件为液固比10∶1(体积与质量比),水解温度115℃,水解时间2.25 h,硫酸质量分数5%。在此条件下戊糖收率达73.78%,底物得率78.67%。
The hydrolysis test conditions of bamboo sweeps hemicelluloses with acid hydrolysis are optimized using the pentose yield as evaluation index.The results show that the optimal hydrolysis conditions are as follows：the liquid （volume） and solid （mass） material ratio is 10 ∶ 1,the reaction temperature is 115 ℃,the reaction time is 2.25 h and the mass fraction of H2SO4 is 5％.Under this reaction condition,the pentose yield is 73.78％ and the remaining substrate ratio is 78.67％.
